| Research Abstract |
The synchronicity in grain growth in a panicle was well evaluated by staining spikelets with iodine-potassium iodine solution using the panicle about 10 days after flowering. The synchronicity in grain growth was affected by temperature and radiation levels and was possibly associated with the endogenous ABA level in the grain. In the chromosome segment substitution lines between Koshihikari/Kasalath, several lines showed specifically low The synchronicity in grain growth, which is hopefully a desired traits in improving grain filling and the association between the synchronicity in grain growth and grain filling percentage was analyzed.
